The Island of Misfit Toys (lildemonlili, ao3)

Pairings: mihyun, nahyo, jeongchaeng, samo

At age nine, Mina is assigned a pen pal as a part of her school's korean program, in order to improve the students' ability to construct sentences and write naturally. Mina keeps contact with the pen pal for seven years until suddenly the pen pal stops answering her letters.

This is honestly so good! One of my fave ongoings as well :) Pen pals for seven years but suddenly halts then -  imma stop right here. as of posting this, it's still 5 chapters in! Join the #MisfitTwice train!!!! lildemonlili is amazing.
